Consumer Electronics

The Internet of Things (IoT) makes our house a smart 币圈交易平台App排名home: effectively an interconnected living area where machines, too, interact with each other. Due to this tight network of and communication between electronic devices via sensors, a house “learns” how best to work according to the requirements of its occupants. For example, it controls and monitors the power consumption, household appliances, heating and ventilation, etc. This smart control increases the quality of life and living significantly, and leads to a more efficient use of energy.

Sensirion’s Developer Website – Get Inspired!

Sensirion's developer website provides developers with ideas and support to launch their own projects with Sensirion's innovative environmental and flow sensors. Information on hardware platforms as well as tutorials and implementation descriptions for interesting applications are available.

For example, there is a tutorial explaining how to use an Atmel board and two humidity sensors to detect whether a device (such as headphones) is on the body or not ("On/Off Body Detection"). Furthermore, you find a tutorial how you can measure the perspiration rate with two SHTW2 sensors.
